I don't believe these will be the first 64-bit ARMv8 CPU cores. Doesn't that honor go to Applied Micro's X-Gene SOCs? They'll ship a lot sooner than 2014.

I would use Evernote more if there were a private sync option, or even a local LAN sync option (which would be usable from my iPhone via VPN). I don't trust my personal data in Evernote's cloud, or any cloud.

Apple CEO Tim Cook also cashed out all of his vested shares around the same time. Does that indicate a lack of faith in the company? No. When you have a ton of shares and the stock is at an all-time high, and you have even more shares ve

I think in the worst case it can be uniform: you can have an average delta value of 100 where the values range uniformly from 0 to 200. I think that case is fine, as you can still encode 200 in less than eight bits, but I'm worried that so

While I believe the author's approach is the correct one, I am very curious to see a proof that an arithmetic encoding will always fall within the 1MB limit. The pigeonhole principle guarantees an average of slightly less than seven bits p

It's not uncommon for interviewers to ask a few warm up/intro questions and then proceed to more advanced questions--so if you didn't get a few questions right, you may simply have missed some easy ones, so they didn't ask you the hard ones

This is my point; that Amazon is a shitty business because they have chosen a terrible sector: retail. That's what you get when your main competitor is Walmart. Look at the absolute profit numbers: 1/40th the profits of Microsoft; 1/100th

There is a limit to how much people are willing to share; this is one of the reasons we still wear clothes.

I think Amazon's profit per employee is around $6K. Compare to Apple at $600K. Amazon is practically a non-profit. Not surprising, as they play in a shitty, ghetto space--retail.

What's funny here is that wireless networks already use FEC at the physical layer. This just adds more, less conservative, FEC higher up for apps where it makes more sense to reduce throuhput and increase some average case latency to avoid

Completely agree. I would also be surprised if this weren't done at the block level, as ZFS does SSD acceleration, rather than at the file level as the article claims. It's just so much more efficient than caching at the file layer, for n

Really? My wifi RTT to the metropolitan core is 15 ms, and over LTE it is 47 ms. Not a worthwhile tradeoff at 40 ms unconditional additional RTT delay. I imagine the higher latency was used to offset lower bandwidth due to FEC encoding lo

by codex 14y ago
Isn't the downside of FEC encoded packets increased latency? Instead of sending each packet immediately, don't you need to accumulate n packets to encode as a group? Or does the math allow incremental encoding? Simple parity is increment

That is one of the more ideal distributions, as each number gets one (zero) bit for delta, and the number at the jump point gets a large but globally inconsequential number of bits. Bits per number is still less than 7.

All of these bizzaro explanations leave me wondering if I've missed something. Can't this be elegantly solved via the pigeonhole principle? There are one million numbers to be sorted, out of a space of one hundred million. That means that

This is just noise. Nobody should care about this release; it's just more commodity software with generic features. With some exceptions, kernels are no longer a key piece of the value chain.

I believe this is correct. I had too few digits of precision in my original calculation; rounding is bad!

In looking at this a bit further, it seems that the reliability of the Falcon 9 is not looking so good. It has only flown four times and suffered single engine shutdowns on two of them (the other: http://www.spacenews.com/civil/spacex-ackn

It should; all of the material quotes in this article came from a SpaceX public relations agent and not from independent space analysts. Not exactly objective. The only quote from Orbicomm is practically a tautology.

It's fun to speculate about this (heck, I may even found a religion around it) but there's no way to prove that one is in a simulation. It's possible that the creators of the simulation do not wish to let the cat out of the bag. Any test w

Solaris has had this for years now with the L2ARC. I'm glad it is finally coming to Linux. Now when is Linux going to get a better page eviction algorithm, like ARC?

You misundersand me. Failures are not due to inexperience. High failure rates are. If a single failure occurs in one out of eight launches, a double will occur once every sixty four. While I believe the Falcon is double fault tolerant,

I didn't know this before, but SpaceX has only done eight launches so far--half of them test flights. Perhaps this explains the anomaly.

There are plenty of things a "great" engineer does differently, but to be "as successful" as those you've cited, you need more than that. There are 1.5M software engineers in the U.S. Your examples are probably in the top 1000--that's the

SpaceX may have speculatively designed the Dragon in advance of NASA's resupply program (though I doubt it: the program was announced only one year after the Dragon began design, and two years after Columbia, when it was clear the Shuttle w

The Space Shuttle was designed and built by a private contractor (North American Rockwell) after a competitive selection process among many private parties; even in the SpaceX case, the funding is provided by the government to private parti

Given that a publically funded manned Mars mission would be at least $10B, a private mission would be difficult even if the cost were reduced 10x. And SpaceX can't even reduce orbital launch costs by 10x over today's gold standard; accordi

Say 1% of papers are fraudulent and 10% have serious errors. Now assume it is 10x easier to prove fraud than to prove, beyond reasonable doubt, that an error was made. The result is that 50% of retractions are due to fraud, but still only

I believe celebritizing entrepreneurship is a good thing. Entrepreneurship is a noble calling that has high social value. To some extent I feel that PG's essays tend to celebritize entrepreneurship. However, I think this a bit of a confli

I'm not sure a company that is losing $30M a month (or $400K per year per employee, of which there are 900) can be classified as lean--and possibly not agile, given that they spent a fortune creating the Roadster only to abandon it three ye
